进或Android的向后兼容性？ [英] Forward or Backward Compatibility in Android?

问题描述

我想知道是否有Android提供任何形式的兼容性即向前或向后。这意味着在黑莓如果发展与JDE 4.2的应用程序，然后该应用程序将工作在任何的手机用OS 4.2或更高版本，这意味着它具有向前兼容性。有什么在Android的相似？

I would like to know whether the Android provides any sort of compatibility i.e either forward or backward. It means as in Blackberry if develop an Application with JDE 4.2 then that application will work on any handset with OS 4.2 or higher which means it has forward compatibility. Is there anything similar in Android?

假设我开发的应用程序与Android SDK 1.5，那么将在具有OS 1.5或更高版本的任何手机的应用程序的工作。

Suppose I develop application with Android SDK 1.5 then will that application work on any handset having OS 1.5 or higher.

希望能得到答复很快。

感谢和放大器;此致 苏尼尔

推荐答案

转发COMPAT在一定程度上保证主要版本。在Android上你的目标的最小API SPEC。只要你不叫私有的API，谷歌保持兼容性向前发展上加入自己的开放移动联盟设备。

Forward compat is somewhat assured on major versions. On Android you target a minimum api spec. As long as your are not calling private APIs, Google keeps compatibility going forward on devices that join in on their Open Mobile Alliance.

这并不意味着别人不能获得Android源，并且打破了所有的兼容性释放自己的基于Android的操作系统。这些设备不会得到谷歌的市场的地方，因为，谷歌测试中只得到授权的设备，以便使用。如果这是你在哪里释放，你可能不会有任何麻烦。

It doesn't mean someone can't get the Android source and release an Android based OS of their own that breaks all compatibility. These devices wouldn't get Google's Market Place because only licensed devices that Google tests get to use that. If that is where you are releasing, you probably won't have any trouble.
